      Achter, Sebastian; Borit, Melania; Chattoe-Brown, Edmund; Siebers, Peer-Olaf (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-30)
      This article describes and justifies a reporting standard to improve data use documentation in Agent-Based Modelling. Following the development of reporting standards for models themselves, empirical modelling has now developed to the point where these standards need to take equally effective account of data use (which previously has tended to be an afterthought to model description). It is ...

Ved Veterinærinstituttet ble det gjennomført histopatologiske og immunhistokjemiske ...
    • Niche separation between two dominant crustacean predators in European estuarine soft-bottom habitats 

      Siegenthaler, Andjin; Wangensteen, Owen S.; Benvenuto, Chiara; Lollobrigidi, Riccardo; Mariani, Stefano (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-05)
      Epibenthic predators in estuarine shallow soft-bottom environments are generally considered to have broad ecological niches with a wide overlap. This allows them to cope with abundant but highly variable prey communities. The assessment of trophic relationships in shallow soft-bottom habitats is, however, challenging and often complicated by the bias and low resolution of the analytical tools available ...
